Omega MDS8PT Owner's manual

Brand: Omega

Model: MDS8PT

Type: Owner's manual

Omega MDS8PT is a universal benchtop meter that offers flexibility for laboratory and various application uses, requiring portable temperature or process measurement. It features a universal input that can be configured for use with a thermocouple, RTD, thermistor, or voltage/current signal.

The MDS8PT is pre-configured and pre-calibrated for immediate use out of the box. It includes two alarm relays and an isolated analog output. The front panel features a 4-digit LED display and dedicated buttons for quick menu navigation.

The MDS8PT offers several communication options, including Ethernet, isolated RS232 and RS485. This allows for easy integration into existing systems or for remote monitoring and control.

4.1 Controls

The UP Button moves up a level in the menu structure. Pressing and

holding the UP Button navigates to the top level of any menu (oPER,

PRoG, or INIt). This is a useful way of reorienting if you get lost in the

menu structure.

The LEFT Button moves across a set of menu choices at a given level.

When changing numerical settings, press the LEFT Button to make the

next digit (one digit to the left) active.

The RIGHT Button moves across a set of menu choices at a given

level. The RIGHT Button also increments numerical values. When

incrementing a digit past “9” it returns to “0”.

The ENTER Button selects a menu item and goes down a level. It also

enters a numerical value or parameter choice.

SECTION 4 CONFIGURATION AND PROGRAMMING

4.2 Menu Structure

The menu structure of the Platinum Series Display Meter is divided into three

mainLevel-1Modes:Initialization(INIt), Programming (PRoG) and Operations

(oPER).

Initialization Mode: These settings are rarely changed after initial set up. They

include transducer types, calibration, etc. These settings can be password

protected.

Programming Mode: These settings are frequently changed. They include set

points, Control Modes, Alarms, etc. These settings can be password protected.

Operating Modes: The setting of this mode allow users to switch between Run

Mode, Standby Mode, and Manual Mode etc.
